16050 Show script python_class name and description

[arthanson]

Fixes: #16050

Removed module name customization from docs as this doesn't look like it worked in v3.7 after discussion with Jeremy.

This looks to address the script name & description but not the module name. Can we fix that as well?

I tried these changes manually on my server and had issue with script.python_class.description - If a script has a field called "description" it will throw an exception:

<class 'AttributeError'>
'StringVar' object has no attribute 'strip'

Seems like the description attribute (probably name and any other attributes) get overwritten with the field vars if there's a field with the same name
Changing it to script.python_class.Meta.description resolved it for me.

We ended up dropping support for renaming the module itself, as it hasn't work for some time and is ultimately somewhat dangerous and confusing.
